My boyfriend and I have been dating for over a year and on day 6 of my cycle, we decided to try out dry sex. He took off all of his clothes. I kept on my leggings and underwear on. He did ejaculate but, to my knowledge, nothing got on me. I did not see anything. I was wondering what is the chance that I became pregnant from this encounter? Also, my boobs have been tender and I have noticed some white sticky discharge. It is day 21 of my cycle and I have not missed a period yet.
